Wiring Electric Water Heater

An appliance for supplying hot water for purposes other than space heating or pool heating.

Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have many uses.

An electric heater used in showers is made of nickel or chrome wire as found in hair dryers or fan heaters, but in this case, the electric heater stay under the water. Sometimes they fail as a light bulb by the use along time, so is necessary to change the heater cartridge such a light bulb.

Uh, circuit is wired pre fuses!

The sub panel I am using for temporary power used to power the electric water heater. The feed for the panel is taken from between the meter and the main fuses. Basically, I cannot shut the power off to this panel!!!!
